Notes from David
The light you need in a greenhouse is accomplished with special greenhouse "fabric".
Indoors and outdoors plants cease to grow when temps exceed 85 degrees, so airflow is essential. Also, with this specially formulated greenhouse plastic/fabric, it will breathe and not build up condensation, or present possible mold issues. It last for 5 years.
Your frame needs to be either aluminum, or cedar, or redwood. I've tried pvc, and they just don't last.
We're building greenhouses with an air gap under the perimeter foundation of double-layered pressure-treated 2X12's anchored to poured cement peers, sufficient to withstand high winds.
The last one we built has removable windows (cedar framed with greenhouse fabric in lieu of glass). Mine will have hinged windows, rather than removeable.
The base of the greenhouse is lined with wire to keep out critters.
You will likely want both electrical and water lines inside the greenhouse, so prepare for that eventuality. Fans will be necessary to prevent fungal pathogens, such as Powdery Mildew later in summer if you live in a high humidity area...just when your crops are coming on!
